I'm curious...does the ring and pinion from the 2014 or 2015 Z/28 fit the Z06 rear end.

Search pulled up nothing, and I'm curious if the gear fits..I'm assUmming not..it would be a cheap route to a 0.391 rear end

??? You want to put a ring and pinion gear from a 2014 or 2015 Camaro in a C6 Z06? I guess I don't understand. Why?

FNBADAZ06

The 2014-15 Camaro Z/28 is equipped with a 3.91 rear end gear. The question, was if the ring and pinion from the Z/28 could be used in a Z06 rear end.

At this time, there is no aftermarket ring and pinion gearset to change from the factory 3.42's in a C6 Z06.

id do that mod in a heart beat if it did.
beats the other $3000-4000 option of puting in a base corvette diff to be able to change the rear gear.

Still surprised someone like Richmond Gear hasn't made a set for this car...

Dan_the_C5_Man

No it doesn't fit, and yes, a large majority of us would be all over that combo if it did.

The_Raging_Bull

which is exactly why I asked the question. My '15 Z/28 comes out of the hole with that 3.91 differential setup like a scalded dog...and like all Z06 owners I am in love with my 2 LS-7's. LMB-Z...I'm surprised you never thought about it, in going from a 3.42 setup to the 3.91 in a Z06 would give you something like a 20 to 30% increase in torque..

Ya know better elapsed time as you accelerate? it'd press you into the seat? Stand Killa SS is right, the only true alternatve is the more expen$$$ive stage 3/4 from RPM Transmissions (stage 4@ 3.90 = $3795.00).

So as an example, putting that transmission in a Katech street attack stage 2 build (630 - 650 hp/590 ft-lb torque), would net you 767 ft lb of torque at 3500 rpm...Yowzaaa! ..thats will hurl your Z down the road to a lower ET -> and it turns it into the absolute bomb for torque..

Back in my college days, I had a 5-speed Mustang 5.0 that came with 2.73's, and all I did was swap out the ring and pinion for some 3.55's...shaved a half second off my quarter mile times. In layman's terms... ~5 car lengths

The_Raging_Bull

I shaved off more than that in my 79 Z/28 with 4.10's (my college days project car) after I had built a forged internals bored and stroked engine with a 200 HP NOS wet shot. As I recall I went from 3.42's to 4.10's, and it was seriously better light to light.

The engine was something like 730 hp; and ran 125 mph 1/4 mile...thats Z06 territory. God help you if you ever tried to get it to corner, but then even corvetes from that time period were terrible in the twisties

MTPZ06

My car was bone stock when I did the rear end swap...that was mod #1 (of many to come ). Think it was about $300 all-in...best bang/$ I ever spent on that car

The_Raging_Bull

I hear you 5 car lengths for 300; great price for immediate performance
It kills me when .Z06 owners don't understand what a simple ring and pinion gear swap does for you...wow....ROTFLMAO

I didn't understand the question at first, but never thought of it that way. I don't race my car at all, never have, never will. My car also makes 525 rwhp. Any more than that and it would be difficult to drive around town, for me. But for someone looking for 1/4 mile or 1/8 mile times, the ring and pinion thing would be the way to go.

Just emailed Richmond for sh*ts and giggles...gave them production numbers of the C6Z, 427 Vert, and ZR1 (without investigation, I assume its all the same rear ), and told them we would like something in the 3.90 range. Told them they would sell if the made them, and currently the only option for these cars is a rear diff swap to a base C6 unit. I'll post up a response if I get one.

Gear set in the Z28 is NOT the same diameter, nor was it designed and manufactured by the same suppliers for these rear axle assemblies..............

Da Z06

They will sell like cold beer on a Texas summer! They would be a back log for months! lol!

The_Raging_Bull

Da Z06 is right. On the off chance they say they'll make them, once they commit to it we should get a list started so we get the first ones. I'm betting they say Nope....

TheSenator

Take my money now. I'd pay $500-750 for a well built ring & pinion set for this car.

The 600whp N/A bolt-on gen4 viper guys are killing us after rear gear swaps. The ones I've seen run like 700whp cars.

Da Z06

How about if we present a commitment to buy a certain number? Given that yhe price is not outrageous which Im sure it may be.

Im sure they would move 1000 sets with fairly ease?

Richmond, Motive or any of them may be interested.

The_Raging_Bull

Hmmm... on axle assemblies...is there any off chance that the Z/28 axle assemblies....designed for use in a Camaro Z/28 differential differential with a LS7 could be lifted out and then made to fit in the Z06 differential?

The Z/28 axle and ring and pinion set are an established mechanical combination which Chevy field tested to establish a car capable of long term use w/o failure. Not being an mechanical engineer, would the need be for a bearing set that would accept the axle assembly to fit in the Z06 differential housing?? If not whats needed- a custom adapter to help make them fit??? That question sounds like you need a solid works rendering so you could drop it in and make it fit on a computer...to determine exactly what you'd need.

The current ring and pinion from the Z/28 work great with upgraded engines. I've been in two built Z/28's which were 625 to 650 hp - they were frigging rockets with that 3.91 rear end ratio. You would swear you're in a hot built C6-Z06. I couldn't feel the influence of the added 550 lbs of weight that the Z/28 has.

LMB-Z

Figure me in on that deal too.
